vThe present-.invention relates to an..improved latch, particularly for,automobiles ef the type having an inside and van outside operatinghandle, andin which the outside handle isadapted to be latched againstvoper-` ation by manipulation of the insidellandle. Thelatchis'especially adaptedfor use upon doersof closed carsbeing appliedto all but one of ,the doors, and which latter is adapted to be 4latchedfromthe outside. l] pa rticu larly propose to provide an outside handleroll-back adaptedito operate uponthe latch bolt.l through anvintermediate retracting member, and anv inside handle roll-back adaptedVto operate upon the latch bolt through a retractingand Kl'atchingmember adaptedvup'onl manipulation in one direction to retract the latchbolt independently of said intermediate member, and in the otherdirection toi operatelatchingmeans,to latch the intermediate memberagain'stfloperation by the outside.V handle roll-back. f

Other objectsareto provide a latch of sim# ple .and inexpensiveconstruction, and. which will be positive and reliable in operation.

sheet metal frame or base plate`10 having a faeeflang'e 11 ben'ttherefrom 'at oneend and within which a rectangular latch bolt opening12 is provided. Aianged-lip portion 13 is bentg inwardlyjrom the` upper`edge of the epening to provlde a bearing for the latch ot. s y y' Thelatch bolt comprises a nose portion 14,

riveted at 15 to a sheetmetal bolt plate orbar 16 guided` at its innerend in a transverse .bridge member 17 having downwardly bent ends 18 and19 secured to the base plate by bent lugs 20 and 21, the bolt bar beingguided at. one edge through engagement with the end 18 and at its otheredge againsta shoulder formed bya bend 22 `in the top ofbridge member. Acoil spring 2 3, mounted `upon the base by means of a clip 24, has itsend en'- ga-ged against a vshoulder 25H01l the bolt,

formedby bending the same adjacent the nose portion 14, and normallypresses the boltA to `its projected portion` An upwardlyV projectvinglug |26 is provided. atthe upperedgeiof the bolt, and isadapted to beengaged by the retracting means offboth the `outside,and insidehandleroll-back, presently tobefjmore fully described.

The outside hanne 'roll-tack 27111515 'it '1mb` 28 rotatably engaged inapertures l29 inthe base plate and ina retaining plate 30.` rlhe plate30 is Vsecured by a lug 31 formed there#` on to the viange 11= andis'also secured supported by a ilangef32 bent upwa dly from thebaseplate and having lugs '32.swaged' in apertures in the plate '30. Theflangel 32`also serves as a guide for', the upper edge of" anintermediate rtracting slide bar 34 engaging -100 the base plate andprovided at its forward end with an upwardly bent iange 35 against whichthe roll back engages. The slide bar 34 is further guided by a lug 36bent upwardlyv from the base plate and engaging the lower edge' and alsothroughvengagement of its upper edge with the/flange 19 of the bridgependen'tly member 17. f l :A projecting lug l37 is provided at the lowerVedgeof theslide bar 34which engages the forward side of the upwarlyprojectinglug 26 of the latch bolt bar, the latch 'bolt spring 23 beingadaptedto normally press the bolt and the bar 34 forwardly against-ftherollback, thereby limiting the'projection ofthe bolt and `yieldablyqretaining ytheY roll-back in' its normal position against the iange 11.

The arrangement permits free retrac'ting` movement ofthe bolt, throughpressure ap-.

lThe forward end ofthe bar 38.y is bent up- Y wardly, as at 40,V intoengagement with .the

'Ver' under surface of the latch bolt bar, and is provided at the upperedge with an upward-V ly bent lug 41 engaging the forward surface of thelug 26 of thel bolt bar, being .normallydisposed in aligned relationwith the lug 37 Y ofthe outside roll-back retractor bar 36, as shownFig. 1. rI he bar 38 projects rearv wardly from thebase plate, whereitis pivotally connectedat 42` to one end of alink 43V which isconnected at its other-end to the remote control inside' handleroll-back 44, 'placed at any suitable point upon the door frame; V l Asclearly shown i-n Fig. 9, the retraction of the bolt throughoperationof'thefoutsidehan- Y 'so the inside handle rollfback and d-leroll-,backand the bar 34 is independent of thebar 38, while, as showninFig'. 10, thev retraction-of thelb'o'lt through operation of y the bar38" is independent ofthe barz34'. p 1 l The intermediateI 'retractingvbar 34 and: the

outside handleroll-back 27 are adapted tof be :latchedl,againstjmov'ement by movement of 'the inside handle rollba'ck' and thebar '38 `in e the opposite Ydirection tothe retractingmovement. For thispurpose 'a transversely slidable latching barv 45 .is mounted beneaththe vrbridge ,member` 17, between the inside .roll- 'back fretrac'tingbaru38iand the bolt bar "16,

being guided at one endI by a .tongue'46' engagvingfa slot`47yintheflange 18 ofV the bridge member, and' atits other end by adown'-wardly bent lug 48 extended through an a2 gular slot 49 in the bar 34and engaged in a rectangularslotO in the base plate. The slot 49 is ofright angular shape, its longitudinal portion v being relativelyelongated and adapted to permit normal retracting movement of the bar-34in the lower or inoperative v position of the latching bar, (Figs. 1 andWhile its,A transverse :portion 1s cofextenslve ,with the slot 5.0Qinthebase plate, andjisl adapt# Ved through engagementV of the lug v48therein, in the upper-or operative position of the latching bar (Fig.l11), to latch the barr34 against movement.

The latching bar is rovided with a downwardly projecting stu 51 engagingla slot 52 inthe 'retracting bar 38,v the, slotted portion ofsaid barbeing embossedV upwardly, as at 53, so as tol provide clearance for theVstud 51 withrespect'to the base plate.
